Sheep anti Human inter alpha trypsin inhibitor

Sheep anti Human inter alpha trypsin inhibitor

• Background: The reactivity of the antiserum is restricted to inter alpha trypsin inhibitor. In immunoelectro- phoresis and radial immunodiffusion, using various antiserum concentrations against Human plasma a single precipitin line is obtained and shows a reaction of full identity with the purified immunogen. In precipitating techniques as immunoelectrophoresis and single and double radial immuno- diffusion (Mancini, Ouchterlony) to identify the presence of inter alpha trypsin inhibitor or to determine its concentration. The presence of non-precipitating antibodies has not been assayed. This does not exclude the use of the antiserum in non-precipitating antibody-binding techniques if proper controls are included.
• CAS Number: 9007-83-4
• Host: Sheep
• Clone: Polyclonal
• Source: Inter alpha trypsin inhibitor is a proteinase inhibitor with a molecular weight of 160,000. Its mean concentration in Human plasma is about 400 μg/mL. It has been isolated as a homogenous protein for use in the antiserum production. Freund’s complete adjuvant is used in the first step of the immunization procedure.
• Assay Principle: Precipitation assays. In immunoelectrophoresis in agarose-plates use 2 μl Human plasma or equivalent against 120 μl antiserum. In double radial immunodiffusion use a rosette arrangement with 10 μl anti- serum in 3 mm diameter center well and 2 μl plasma samples (neat and serially diluted) in 2 mm diameter peripheral wells. In electroimmunodiffusion (Laurell) use a concentration of 1% of the antiserum in the gel.
• Form: Delipidated, heat inactivated, lyophilized, stable IgG fraction in ½ diluted; Normal serum; No preservative added IgG fraction 13 mg/mL in; Normal sheep serum diluted 1/2 with PBS; No foreign proteins added; Reconstitute the lyophilized antiserum by adding 1 mL sterile distilled water
• Precautions: This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving Humans or animals. This datasheet is as accurate as reasonably achievable, but Nordic-MUbio accepts no liability for any inaccuracies or omissions in this information.
• Storage Conditions: The lyophilized antiserum is shipped at ambient temperature and may be stored at +4°C; prolonged storage at or below -20°C; Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2); Repeated thawing and freezing should be avoided; If a slight precipitation occurs upon storage, this should be removed by centrifugation; It will not affect the performance of the antiserum Diluted antiserum should be stored at +4°C, not refrozen, and preferably used the same day
